SPECIFICATION forming part of Letters Patent No. 225,313, dated'lVIarch `9, 188. Application led January 24, 1880.

To all whom 'it may `concern Be it known that I, FREDRICK WITTEN- METER, citizen ofthe United States, residing at Columbus, in the countyof Franklin and State v above a perforated grating-surface.

shown in Fig. l, and Fig. 4. represents a vertical. cross-section through the center of the box when in the position shown in Fig. l.

A designates areceiving-box, into which the gratings fall, and which fornisa base for the other devices hereinafter described. The ends of said box A are provided at their top edges with transverse lianges or ledges a, extending from side to side of the box and serving as guides forV the lateral withdrawal of gratingplatform B when the grating is finished. This platform B extends longitudinally beyond said receiving-box A, to give room for the vibration of the vegetable-holding box or 1frame hereinafter described, and is provided on its side edges with raised side pieces, B,in which are formed longitudinal grooves or guideways b. The middle portion of said grating-platform is cut away, and the opening thus made Fig. 3 repreis covered with a perforated dat grater, G, Whichfextends over the whole interior of receiving-box A. At the ends of this grater transverse strips of rubber or other suitable material are fastened to the top of platform B. These strips (marked c) extend far enough at each end to prevent the escape of any particles of the vegetable in either longitudinal direction while the vegetable-holding box or frame is traveling back and forth, as hereinafter described. On the bottom of said platform B are secured transverse guide-pieces B2, which arerecessed at b2 to receive the dan ges or ledges a on box A, above mentioned.

D designates a bottomless vegetable-holding box or frame, of rectangular shape, and provided at the bottom edgesof its sides with beads or guide-Han ges d, which set into grooves or guideways b. This box is of sufficient size to cover `the grater C, and of any convenient depth.. It tapers internally from top' to bottom, so as to have the shape of a hopper or funnel of slight inclination. This shape facilitates the introduction of the vegetables to be operated on, but causes them to jam tightly together at the bottom of box D, so as to obtain the best possible results from the action of the grater C below.

E designates a follower adapted to pass down into frame or box D, forcing the vegetables through the grater as fast as they are comminuted thereby. Said follower is :made

smaller than the upper end of the vegetable- Y holding box-or frame D, but fits exactly the lower part thereof, so that no particles of the vegetable will pass up above said follower when the grated, or partly grated, layer of vegetable is reached by said follower. To insure accurate fitting] between the latterl and box D, the sides or edges of said follower are beveled, having the same inclination as that of the inner faces of said box.

The construction of the follower E and box D, as above described, prevents said follower from passing through said box so as to press against the grater. It is more serviceable for this purpose than stops of any sort, since it does -not allow fragments of the grated vegetable to collect where they cannot easily be dislodged. It is also a stronger and more reliable contri Vance. The said follower E is proi vroo vided on its top with a handle, F, and graspingrecesses G. By means of this handle and these graspingrecesses the box D can be moved backward and forward longitudinally to grate the vegetables contained therein. By means of said handle the box D, grater C, and plat form B can all be laterally moved off from the receiving-box- A, which can then be readily dumped or otherwise emptied. This separa tion may be total or partial, as seems most convenient.

I do 'not conlne myself to any particular material for the construction of my improved vegetable-grater. Most of its parts can be made cheaply of wood and will answer every ordinary purpose, but any suitable metal may be employed` instead. Other changes may obviously be made without departing from the spirit of my invention. l

rIhe entire working of the device from the time box D is charged until the time box A is left open for emptying is by means of the handle F with the aid ofthe recesses Gr. These recesses afford a firmer hold to the operators hand; but they are not indispensable.

that is necessary is to set the box A on a table or other support, and steady it there by one hand; then grasp handle F with the other and work it back and forth in a longitudinal direction, giving it full sweep and bearing moderately on the contents of box D till the bottom thereof is reached; then move said handle to the right or left until the receivingbox A is left uncovered for emptying.

The construction of platform B allows along and effective motion of box D for grating, and

All

the tight fit of said box and follower, together with the presence of flexible strips c and side walls, b, prevents the loss-of any part of the material operated on. The machine itself will be very little soiled, and the operators hand is fully protected. There is no need'to open or unhinge any part of the device., yet it is readily taken apart for cleaning'. I have described it as used for grating vegetables; but it can obviously be applied to other substances also.

Having thus fully described my invention, what I claim as new, and desire to protect by Letters Patent, uisl. In combination with receiving-boxA and platform B, attached thereto by transverse guideways and having grater 0, a vegetableholdin g box o r frame, D, attached to said platform b vlon gitndinal guideways, and a follower, E, having handle F, whereby box D is moved longitudinally, and box D and platform B laterally, at will, substantially as set forth.

'2. In combination with receiving box A, platform B, and grater C, the internally-tapering or hopper shaped vegetable -holding box or frame D, and the follower E, having its edges correspondingly inclined, and adapted to fit tightly the interior of said box D at the bottom thereof.

In testimony whereof I afx my signature in presence of two witnesses.

FREDRICK WITTEN MEIER.
